03wrx more power wanted ?
Just goit myself another wrx and its a standard 03 blobeye , think its a uk one but not sure (didnt ask and didnt know the difference!) .
It has a racebox rear silencer on it and ive just added a green panel filter as ive heard good reports about them .
Ive been thinking of getting a full prodrive system (used) sports cat , decat pipe , center and back or am i better of getting a different cat back system instead like hks or blitz (dont want to loud though!) ?
Then an ecutec remap ? whats this 3 port i keep seeing pop up in threads ?
I want more power than standard so ive done filter so would exhaust and remap be next ? will an sti topmount make a difference ?
i dont want big power and to spend loads otherwise you might aswell get an sti but i just want a bit more ooomph

Full exhaust with Sports Cat and a remap should see you around 270-280bhp - whether its Prodrive/HKS/Blitz etc.
Don't need to swap for an STi topmount at this power.

Oh and a 3 port boost solenoid is just able to provide better control of boost.
I needed one on my first remap as the mapper couldn't hold required boost level - they are not necessary most of the time IMO.

3-port only required at stage on if your original is a little worn, generally the factory boost solenoid should be okay. I'm changing to a 3-port at stage one because it is one less thing to worry about when I fit the bigger turbo and head towards 400bhp

some exhausts have a better flow than others, not too sure which is the best. i know the scoobysport backbox is known for its good flow so might be worth a look ScoobySport - Performance Exhaust Systems for the Subaru Impreza
post a thread im sure someone will be able to tell you the best power wise

If your budget will stretch then a 2nd hand turbo (VF35 or VF34) will also help as the standard turbo runs out of oomph in the higher rev ranges. Have a WRX with PPP and just had it remapped after fitting a panel filter and second hand VF34 - the difference is immense!
